The present invention relates to improvements in plows .and has particular reference to a plow arranged to carry a novel form of heel sweep.

5 An important object of the invention is the provision of a plow having a sweep securedthereto, the plow and sweep being designed to provide a durable and eflicient structure.

A further object of the invention is the provision of a plow sweep of a simple and durable construction which can be firmly attached to a plow.

A still further object of the invention is 15 the provision of a heel sweep which can be readily attached to the standard type of plow and which may be manufactured at a comparatively low cost.

Other objects and advantages of the inven- 2 tion will become apparent as the description progresses. V

In the accompanying drawing forming a part of this specification and in which like reference characters are employed to designate corresponding parts throughout the Same:

Figure 1 is a side elevational View showing my improved type of plow and heel sweep,

Figure 2 is a top plan View of the same, 7 Figure 3 is a vertical longitudinal sectional view through the assembled structure,

Figure 4 is an enlarged transverse sectional view taken on the line 4- of Figure 3, and

Figure 5 is an enlarged fragmentary perspective view of the plow shovel showing the construction of the upper portion thereof.

As will be well understood by those familiar with this .art, the plow structures com monly employed at the present time, particularly plows employing heel sweeps, are not entirely satisfactory due to the inefficient sweep connection. During use, the sweep is subjected to rather severe lateral strain, and the conventional pivoted connection soon becomes loosened so that the sweep is permitted to vibrate or assume a turning movement relative to the plow foot to the detriment of the plowingv operation. With this in mind, my invention resides in the provision of an improved plow, adapted to accommodate a heel 1928. Serial .N'o, 270,425.

sweep of special construction and having an adjustable lead plow or shovel of simple design formed to prevent angular movement thereof.

' Referringto the drawing, wherein for the no purpose of illustration is shown the preferred embodimentof my invention, the numeral 10 designates the beam of my improved plow, this beam being formed with parallel side ribs connected by a transverse central connecting rib, the beam being curved in the usual manner and producing inner and outer channel shaped, grooves. A transverse opening is formed. in the lower or foot end of the beam for detachable connection of 'a shovel orlead plow 11. i j

p The lead plow 11, in this instance, is of generally rectangular formation having its lower end out in an angular manner to produce" a suitable plow point, and its upper end bent 7 slightly outward for suitable connection. The intermediate portion of the shovel 11, adjacent the upper end thereof is provided with a longitudinallydirected elongated slot 12, transverse projections being formed at 7 the ends of the slot to provide holding lugs 13. As shown to advantage in Figure 3, the shovel 11 is attached to the plow beam 10 through the instrumentality of a bolt 14 ex tending through the elongated slot 12 in the shovel and the opening in the beam. The lugs 13 are formed to readilyengage the inher groove of the beam 10'so asto prevent angular movement of the shovel. From this construction, it is obvious, that the shovel will be durably connected to theplow beam and held in a vertical position by means of the lugslS. Thus, the lead plow may be conveniently adjusted to compensate for wear} or toregulate the depth of the furrow.

- Animportantcharacteristic of the'present invention is the provision of a plow sweep of special design adapted to be snugly fitted in association with the plow beam and secured in positionthereon, the sweep being arranged to engage the outer channel in the beam and is thus retained against turning movement. This sweep embodies a central body portion in the formof a transverse plate 15 and a.

pair of diverging angularly arranged legs 17.

Formed at the center of the body plate 15 is a substantially U-shaped outwardly projecting bracket 16 engageable with the outer groove in the plow beam. A suitable opening is formed in the bracket engageable with the bolt 14, arranged at a position opposite the elongated opening of the plow shovel 11, as clearly illustratedin Figures 3 and 4. As. can be readily noted from the drawing, the legs 17 of the heel sweep are bent transversely at an angle, so that the lower edges assume expanded positions relative to the upper edges. Although the sweep may be directly secured to the beam by means of the securing bolt 14, I contemplate a more convenient and durable method of connection, embodying the provision of a backing plate 18 of rectangular formation adapted to be placed in contact with the rear of the sweep body, this plate be- 20 ing provided with an opening arranged to align with the opening formed in the sweep body and plow beam for engagement by the bolt 14. With this arrangement, the backing plate '18 will extend across the bracket projection and cause the head, or nut of the bolt 14, to project outwardly thereof so as to permit convenient engagement by a suitable tool.

Thus, it can be readily seen, that a simple and durable plow structure has been produced, providing a heel sweep of compact and durable construction arranged to be firmly secured to the plow beam. The invention further contemplates a compact yet simple lead plow or shovel connection arranged to permit as, convenient adjustment of the shovel relative to the beam. I

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the 4 same and that various changes as to the shape,

size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I

claim:

In a plow of the character described, a beam formed with a rear channel, a. heel sweep consisting of a comparatively broad flat central body extending transversely at the rear of said beam and havin arms diverging rearwardly'therefrom, said body having its central portion bent to form a U-shaped bracket fitting snugly into the channel, a broad fiat bridge plate extending across said bracket and bearing against the body at opposite sides of the bracket, a shovel fitting against the front of said beam, and a bolt extending through the bridge plate, bracket, beam and G9 shovel, as and for the purposes set forth.

In testimony whereof I afllx my signature.

JAMES LAIVRENCE MOGEE.
